ANSC 1001 Lecture 16: Growth
Document Summary
Digestive tract to extracellular nutrient pool (partitioning of nutrients from metabolize pool), and depot nutrient pool (muscle, bone, fat) Cellular changes in tissues and organs leading to different roles, functions, and greater complexity. Ratio of the head to the body changes as the tissues and organs in a human develop. When you have that development occurring, but the form does not change like you see in the humans; the ratio of the parts stays the same. Fish display this type of growth because they do not experience gravity like humans do. The type of growth humans experience where ratio of the parts of the body changes as the body develops over time. Increase in cell number (does not necessarily mean the cells get any larger in size) Example: progenitor cell gets signal to become pre osteoblast, then a mature osteoblast, and so on. It is critical for species to develop from conception to maturity.
